This invention relates to what we-shall for iconvenience termi a.locomotive. We sa jjfOI'COI'lV GIllGIlQG, owlngto the fact that the11117611131011 when incorporated in a machine such asa locomotive, 1s ofparticularutility.

heat in the carrying into effect of our aims.

It is possible that all the features of the inj vention may not bepresent many one case;

that is they dividually.

In the drawings accompanying and forming part of the presentspecification we have shown somewhat in detail, one of the several formsof embodiment of the invention which may be employed jointly or in toenable those skilled in the artto practise the same, will beset forthfully in the following description. We are not restricted to thisparticular disclosure; we may in fact depart therefrom in severalrespects within the scope of the invention defined by the claimfollowing said description.

Referring to said drawings:

Like characters referto .likeparts throughout the several views whichare on somewhat different scales. i

we have already observed it "is within the bounds of possibility thatthe features of the invention may be employed with advantages in alreadymade it clear that the title selected, is merely for ity in such a use,whichlis illustratedsomewhat fully in the drawings. The locomotive shownis denoted eral way by 2 and its tender by 3, merelythe forward portionof the latter appears. The locomotiveincludes in its strucin a gentfirea boiler as 4 and back of the same is t e 1 pendant fire box .5 underwhich is the 3S PI'OVldGdfWlth the waterfspaces 7 and the tubes- 8through which pass the products of combustion from thefire box'5 to heatthe water in said water spaces 7 as is usual.

This structure need be I but briefly described It is a matter of factasalready virtually observed, that the efficiency of a locomotive isseriously affected a in cold and wintry weather to such an extent infact as tests have proven, that it is lowered to a very small point,this applying to the fire also. This is one of the'objections weovercome. This is accomplished as illustrated by a jacket such as thatdenoted in a general way by 9. This jacket incloses partly or completelythe boiler 4, its front end being connected with the smoke bonnet 4 ofthe boiler smoke space or interval being designated by 11. There may beif desired and as shown, strut or braces 12 between the boiler andjacket. V

The rear end portion of the jacket or shell 9, has depending extensions13, 14 and 15, the extension 13 being in frontof and spaced from thefront of the fire box 5 and ash pit 6 respectively and the sideextensions 14 and 15 being laterally spaced from the COI'I'G'; p miParticle o said fi e 199K and ash many "different ways, havingconvenience and for the fur-' ther fact that the invention isof primeutilalthough p1t6 as quite common. Theboiler 4; is

fire box we are enabled to adequately against the temperature-loweringeffects of air blasts such as are invariably present 111 cold and snowyweather. While the'complete jacketing of the boiler and the fire box andash pit are desirable it may not be always necessary thatithe severalportions cases it may be necessary to merely jacket the boiler while inothers the fire box and the ash pit. n

Thewaste gases and products of combustion are generally discharged atthe front end of a locomotive. Vi e prefer that these be led off at therear portion or as nearly as practicable the rear end; certainly back ofthe front end. In this way we utilize these waste gases for increasingthe efliciency of the boiler as will be hereinafter set forth.

The space 10 at'the front of the boiler 41: serves conveniently as areceiver for an injector of proper kind, that denoted in a general wayby 16 meeting our conditions. Said injector is of annular or circular,tubular or hollow form, being located within the space 10. The injectorreceives its hot agent, in the present case steam, in the form ofexhaust from the cylinders 17 It has asshown a base or foot 18 restingon the bottom of said space 10, said base being secured rigidly inposition in some convenient manner. The base, or foot of the injector isconnected bypa'ssage means such as denoted in a general way by 19, withthe exhaust ports'of the twocylinders 17 in "view of which circumstancethe exhaust steam from said cylinders,can pass byway of said passagemeans 119 up into the interior'of' the injector 18, Said injector ormore properly its body is furnished with a series ofrearwardly-dire'cted annularly-arranged nozzles guard.

1' around the i301 ,way of a stack a a the rear end of 'be thus acketed.For example in some portion of the stack 20.

Witnesses I 20 which extend into the space 11 so that the exhaust steamcan be directed into said space and can pass rearwardly, circulating"ler 4 and also at opposite sides of the fire box 5 and ash pit 6respectively, ultimately passing to atmosphere by as 20 situated asnoted, at the jacket 9 and extending through the roof of the cab 21.

A locomotive is usually equipped with air-brakes, and the means by wlnchenergy is ordinarily derived to effect the operation thereof, isobtained from an air pum as 22 driven by a steam motor as 23. he exhaustfrom this motor 23 passes into the pi e 24L which terminates at itsdischarge endin a ring 26 located in the lower end Thus this exhauststeamvfrom the air brake motor is'utilized for promoting the draft. I

The space 11 is closed at the rear by the wall 30, extendingbetween theboiler 4 and the jacket 9. This wall has openings normally closed by thedoors 31 by 0 ening whichthe said space may be cleane when desired, asby blowing steam or air through the space fromeither end of the boiler.

f Vhat we claim is:

i The combination in a steam engine, comprising a boiler, a jacketaround and spaced from the boiler, and means for causing the exhauststeam from the engine to pass along said space and at the same time tocause the waste gases of the boiler to travel said space. In testimonywhereof we affix our signatu'res in the presence of two witnesses.
